pro-sites page shows up blank

Hello, when I go to my site’s page, its completely blank, no tables, no prices, nothing. When I switch to the default theme it shows up. If I change the template from default to services, it shows up all ugly, but on the defualt nothing.

How can I start to debug this? I don’t know where to start or what to do. Please help, I bought this theme especially for this project, I dont want to change it.
